The most popular solution to slab heating is radiant floor heat. The wonderfully comfortable and even in the winter but does suffer from long reaction times, making it less than satisfactory when the weather goes from heat/cool/heat in the course of a day during the shoulder seasons.
If YOU want change, YOU have to first change.
If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!
Need more details. Where do you live? Fairbanks or Baton Rouge. If in a floodplain, are you in the 100 year or 500 year and what was the elevation of the water at the last flood?
This asked, my favorite heat is insulated slab on grade radiant. Relatively inexpensive compared to other radiant installs and has the benefit of "banking" millions of BTU's at low temperatures. If you live in a high daily temp swing area you can typically get by with a smallish heat source and focus on efficiency. Add out door reset controls that have some brains and it will accommodate you quite well with unbelievable comfort and then economy of operation. Oh, and noise and draft free too.
